I am developing a 3d configurator. A cube appears on the scene. If you click on the side of this cube, a rectangle appears. The problem is that if I click on the same side of the cube, another one will be added over the existing rectangle. I would like to block the clicked side. My cubes and rectangles is buffer geometry. I can get raycasting face (a,b,c) and faceIndex. But how to get intersection of two different faces of two different objects? Sorry for my english

This is my project https://alovert.ru

my code

```
if (intersect) {
var index = Math.floor( intersect.faceIndex / 6 );
if ( intersect.object.name == 'cube' ) {
switch ( index ) {
case 0: load( intersect.object.position.x + 6.58, intersect.object.position.y, intersect.object.position.z, 'beam', 0, 0, 0 ); break;
case 1: load( intersect.object.position.x - 6.58, intersect.object.position.y, intersect.object.position.z, 'beam', 0, 0, 0 ); break;
case 2: load( intersect.object.position.x, intersect.object.position.y + 6.58, intersect.object.position.z, 'beam', 0, 0, 90 ); break;
case 3: load( intersect.object.position.x, intersect.object.position.y - 6.58, intersect.object.position.z, 'beam', 0, 0, 90 ); break;
case 4: load( intersect.object.position.x, intersect.object.position.y, intersect.object.position.z + 6.58, 'beam', 0, 90, 0 ); break;
case 5: load( intersect.object.position.x, intersect.object.position.y, intersect.object.position.z - 6.58, 'beam', 0, 90, 0 ); break;
}
}`
